In this mammoth episode, we’ve got some random CES observations, a review of the Avantree Bluetooth over-the-ear headset from George from Tulsa, a CES interview with an innovative hearing aid called Eargo, a story of Thunderbolt docks and USB-C from me, another CES interview about LiFi for Internet connectivity with OLEDcomm, a hot tip from Knightwise about how to reinstall Mac App Store apps using the command line, an augmented reality toothbrush from Kolibree called Magik from CES, and as if that weren’t enough content, we’ve got an out-of-band Security Bits update with Bart Busschots with the lates news about Spectre and Meltdown.

This week the irrepressible Knightwise of knightwise.com sent in an awesome tip via audio, and it’s too good not to share in text as well. I’ll do my best to do it justice. I’ll start with the problem to be solved (of course) and then give a little bit of background and then his tip. Finally, I’ll give you bonus tip from me.

The problem to be solved is finding the easiest way to reinstall apps you’ve previously downloaded from the Mac App Store, especially when doing a nuke and pave, or moving to a new Mac but you don’t want to bring along the cruft you’ve collected over the years.
